Yup. As I said (perhaps in an email don't remember what part was posted on your thread, my thread, and in private messages), The only *good* t5 options are going to be an icecap SLR, Geissman (sp?) Sfiligoi, and ATI. ATI is kind of out because although its rumored they make a 120v US 5" pendant, I've never seen it and I looked and called everywhere.
That leaves an Icecap SLR (Or tek SLR, but imho the Icecap is better) or one of the pendants. Both pendants are gorgeous and although its a shame to hide them, They are not much more than an economy built SLR. I priced the aluminum to build a "real" SLR and it ended up being pretty much a few hundred bux less than the pendant... not really worth my time. You could build the light rack out of PVC or wood, but IMHO its not a good long term solution.
That leaves the pendants. I like the Sfiligoi over the Giesmann because it had more bulbs. That was pretty much my reasoning.
The cheapest way to do the whole thing is to do MH lighting with VHO or t5 supplementals. You'll be forced to build an aluminum rack yourself or spend money on a pendant that would be just as much as a t5 pendant. But if you build the rack you can save a ton of money because the components for MH are cheaper than t5. But as I mentioned before I wanted the ability to fiddle with colors that T5 gives and I wanted to be able to run sections of the pendant at a time... something you can't do with MH.
