Nah. $250 for a gun that needs $100 worth of parts kits is just plain dumb. Also, anyone who can lose that many screws and hoses off a freakin' Vector probably abused the

out of it.
I got one that I still cry over--worked great until I stripped it down for cleaning, couldn't figure out why one of the four tiny HP line block bolts was coated in epoxy until I found the thru-reciever threads stripped out and the whole gun shot--and since then I've been somewhat leery of eBay guns that look beaten up. I'm tempted to send it to someone good like Doc, but frankly it would just cost too much to have the thin, tiny wall of the reciever fixed so it would hold pressure again.
