My advice to you ... is be very careful. Take the Judson's units for example. Les and his wife are great people. I buy all my chemicals, that I can, from them, and Les has bent over backwards to help me repair my current unit, even though it's not one of his. So, when I am shopping again, Les at Judson's will be the first person I call. However, having said all that, just because Les is popular on the boards, does not in any way reflect favorably on his rigs. I've seen too may darlings of the week on the internet who actually make shit for units. So shop carefully.
In fact, I was just discussing this with the bucket head Himself today. Why is it that nobody who makes TM's, and also stalks the bulletin boards actually incorporates the bulletin board improvements that we all want? Do any of our favorite mfg's make rigs with 3 or 4 inch internal plumbing and 2.5 inch vac ports on their waste tanks? Are 2.5 inch hoses and glided 2 inch wands being supplied as standard equipment on anybodies packages? Are any true dual wand units being made?
If I were paying 25 K for a new slide-in, it darn sure would have all the upgrades I want, or else I might as well just shop for the lowest price. No sense in paying a whole lot for more of the same.
We've come too far in this industry for manufacturers to be able to get away with not keeping up.
Oh, and I know DooDaddy is gonna chime in saying he has one on the way, but I'll believe it when I actually see it.
