I am doing a V1 right now and it's a breeze so far. I even converted a CW V1 found on ebay for $650 with all new bearings. Found a CCW volute and a 928 motorsports impeller and it's a done deal. Bracket and misc stuff came from superchargersonline.com. Made the tubing from various aluminum pipes on ebay and silicone couplers.
Tons of used kits are going too, and I would recommend looking at Prochargers (P1SC's) and Powerdynes, etc. Vortech is like the microsoft of superchargers, big bloated, and unresponsive. Expect zero help from them when buying a used kit if you have a question. All they want is for you to send them the unit for a rebuild, period. Nothing wrong with Vortech units but there are tons of alternatives that are just as good if not better. Bottom line, if you find a good used deal with a bracket it dosen't matter the brand- they are virtually all the same.
If you find a really good deal for a Vortech V1 or V2, make sure the impeller is good (no bent fins, etc). Bearing kits are around (superchargerrebuilds.com is very good) for around $250-350 and if your good mechanically you can rebuild yourself.
After I am done I will post pics, vids, and a guide on the process.
