I worked all summer to afford a 1998 Autococker, which I used twice before promptly ruining it with unnecessary and poorly-selected aftermarket parts and bad timing. Of course, at the time "high-end" was basically anything nicer than a Spyder or Pro-Lite. I held onto it, constantly trying to configure it the way I liked up until 2010 when I traded it for a PGP to sell.
The only time I've ever owned something that could have, at any time, been considered a best-of-the-best gun was a few years ago when I briefly had a modified ECX Intimidator. By then it was severely dated in terms of its size so I sold it before ever bringing it to the field. Kind of regret that, as back in 2002 I would have killed for one of those things.
