There's a system with all the hookups (with RF) for $150, the game Rayman (loose) for $70 both on Lukiegames.com, and I'd like to find a composite cable which seems to go for about $25. I just don't know if I want to take the plunge... I would love to have all of that but I wish I could get it all for a bit less than that...
That's awfully high IMO, especially for an item I can't see in person first. If I saw the system in person, it was in fantastic condition with the box, manuals cables, controller, etc...I
might drop $150 on it. Might. And that would be partially based on an impulse buy. Sight unseen with no idea of the condition or if any original materials are with it (more than likely not)? No way. $70 for Rayman is absolutely ridiculous, especially a loose copy that's probably beat all to hell.
I've seen Jaguar's come through the local mom & pop shop occasionally and I think the most they asked for the system with a game was about $75.
If you are seriously wanting one, I would suggest advertising on your local Facebook Buy/Sell/Trade pages (they have them for just about everywhere). Even if one is not listed on their, you can make a "listing" that you are looking for one. You would be surprised at crap people have in their closets collecting dust that they would be more than happy to sell you for $20 or sometimes, even give it away to you.
If you are wanting it to sample the handful of decent games on the system, you can do better elsewhere. The best game was Alien vs. Predator, and an enhanced version of that was released for the PC. Rayman can be had for PC, PlayStation, Saturn, etc. for about $20 for a complete, great condition copy of at least a Greatest Hits version.
