I've got a Vibe if your interested, it needs a front barb banjo fitting for the front of the board (can buy from smart parts uk) but otherwise its in perfect working condition. I bought it in bits and used some parts off my G-1 to make a complete marker, these include the barrel, feedneck, trigger and the Regulator. I also replaced the O-rings and detents with new ones from my spares kit and replaced the steel braded hose with the macro line and fittings. The only other thing to note is that the grips are worn and starting to split in some places!
I paid £60 for the Vibe parts and then added my spares to replace what was missing. If you're interested make me an offer?
