Rear shock dilemma...

I also posted this over in the shock forum so I appologize for the cross-post, but as I'm a clyde I figured I might get some more pertinent info here too.

Ok so here's the deal. I have a '99 Trek VRX300 which has been my main & only bike for a number of years. Yeah, yeah I know it's out of date and wasn't the best design to begin with, but it's done the job just fine. Anyway, I've been lucky enough to not have had any major issues with it other than typical maintenence niggles (tires, pads, et cetera). I'm a 6'4" 200lb.+ clyde to boot so no complaints here.

Anyway, the rear shock has finally given up the ghost & I'm not sure what route to go to remedy the situation. It's a Fox Vanilla R and I've already contacted PUSH Ind. about having it rebuilt, but it's too old so they are unable to service it. I've searched high & low to find a rebuild kit for it or at least info about it to no avail. So, I suppose my final solution is to just straight-up replace the shock altogether. Buying another bike right now is financially out of the question otherwise I'd just go that route.

So, I guess I'm just wondering if anybody out there has any suggestions about which route to go? I'm not looking to spend a whole lot as the bike is rather out of date and I don't see much point in dumping a bunch of money into it anymore. However, I'm itching like crazy to ride and other than the rear shock issue the bike is good to go. So, is there a rebuild kit out there for the older Vanilla R's or another route I can take to get it fixed? Or would I be better off just getting a new/used shock to replace it? I've found a few "deals" online that seem like a possible solution, but I'm not sure if it's worth it. I've found some NOS Vanilla RC's which are several years old (unused) which have the proper dimensions and are a decent price. Would that be a viable option? I've also looked into the Cane Creed AD-5 and AD-10 both of which pop up on eBay every so often for reasonable prices. Oh, and I also found a decent deal on a Swinger 3-way air shock. I have no preference between spring or air shocks.

Any insight into this would be greatly appreciated.

Thanks in advance....
