I'd got with Scat cranks and rods regardless.
About the only thing TMD is good for is misc parts. I've ordered a main support, and various other smaller items like that, and the service was 'ok'. The parts ordered were what I wanted and expected. However when it comes to important, and by this I mean rotating assembly/valvetrain parts, I'd go with someone reliable. We've had good luck with Flatlander Racing at:
Great prices, good service, lots of info, and they'll work to get you what you want and/or need.
All in all, with a lot of the Ebay sellers you'll run into the same thing. Poor quality, and if they don't have what you want in stock...and you push them, you'll get whatever's on the shelf. I've heard of people getting SBC 383 crank kits instead of 347 stuff lol. This is true regardless of what you're buying. I collect Japanese swords. Do a search for 'Katana' on Ebay, and you'll see what I mean!
Anyhow, good luck with your setup, hope this helps!
