Indeed, all I purchased from the store was some cans of paint and I gave them a really funny look the whole time after they said "what's GS?"
I haven't been there since =)
Maybe things are different up here in the northeast. Honest to god, all four hobbytown usa's I've called (mostly around boston) do not stock any GS stuff at all, even silicone type things. It's really odd.
I have kinda a different view on parts being the deciding factor on choosing a buggy. I guess that's because all the buggies are equally unsupported =) You have just as much luck finding a GS part then you would the Ofna part you need. And forget about anything more exotic like Kyosho or XTM parts. My view is if you can get parts online at a good price and easily, then you're okay.
I am slowly building a stock of replacement parts for my buggy. I know I'll never have ALL the parts I'd ever need, but then again when was the last time your radio box broke, or both bulkheads at the same time? So far I've had any parts I need for a repair in my own box.
