Ok, I finally have gotten around to having a little more free time, so I can type a little more.
I don't have any experience running a TW at all. The things I didn't like about TW, when I was seriously looking was that you had to pay more for the extras that came standard on other machines (the log lift and 4/6 way wedges and table grate). I finally saw one in person at the state fair and well the sales guy really turned me off. You could tell he was just there for the sale. I didn't get to see it run nor get a good look at how it was put together. The more I read and saw what others used, the more I wanted to steer clear of them, for the other features that I liked on other machines. I do like the 2 stage vertical wedge of the All Wood, especially for those goofy pieces that weren't cut right on either end. Another thing I saw was the jack near the end of the wedge end. When using the log lift, if you get a heavy piece on there, you must have something under it so that the splitter doesn't tip (assuming you have it disconnected). For my own experience this worked great, cause I used my atv to move the splitter into position, and then I could use my atv to skid wood to the splitter. Again, a small feature that I think worked out greatly in my operation. Another is the wedge design. Having the notch cut out in the middle helps keep the wood down, or from riding up, and for the special pieces I mentioned previously. I did not like TW wedge design. I didn't like how the 4 way wasn't hide-able on the TW, and that it's not attached to the cylinder. Granted you can change wedges very quickly on the TW, but I found myself hardly ever changing. I did I think twice, change from one to the other, and it was just to try out the different wedges to see which worked greater for me. I wouldn't pay extra for a 6 way, I'll tell you that, which was another reason I went with All Woods, cause it's included.
Again, I'm not saying TW is a bad machine. I think they all work about the same. I think you will get more bang for your buck with All Wood, and the options on one, are standard with All Wood. I can't speak for Built-rite. Their specs look pretty good. At the time when I was looking though, their price was out of my range. I think what they build compared to All Wood, is fairly close, but I know All Wood would be cheaper. You should give Bobby a call if you have any questions. He's very knowledgeable and easy to work with. He could answer any questions you have. I've had to call him a few times with some questions, and he's been very helpful and explained things very well. Only once I called and he didn't answer, but he called back less than 10 minutes after I called. So he has great customer support.
I know you've got a touch choice to make. In that range that you are talking about, I don't think you'd go wrong, you'll still get a great machine. It's just my opinion that you will get a little more from All Woods, but that's only based on my experience with one brand of machine.
Can I ask, why the redwood series vs the musclewood? The extra tonnage? While you get more tonnage, your cycle time is a lot longer, 12 seconds vs 6 seconds. Again, it's about what and how your operation operates. I'd like to have the ability to go faster with mine, but it's plenty fast at around 11 seconds (I run about 60-70% throttle, is why it's slower then the 10 as advertised) for me and my cutting buddy.
Hope that helps. Be sure to post back, maybe some pics with what you get and such when you do get a unit.
