[quote name='petersa1d']anyone have links to cheap guitar hero controllers? ps3[/QUOTE]
I don't have any links to the best place online to find them cheap, but if you have a Disc Replay they usually have a nice assortment for $5-$20 depending on which guitar you want and if you take any games bundled with it.
By far the best guitar controller I've found is the current GH5/Band Hero controller. There was a guy on ebay about a couple months ago selling multiple copies of Band Hero w/the guitar for 18 plus $6 shipping. The Band Hero setlist isn't that good but at the local game stores the guitar goes for around $20 by itself so it was a good enough deal for me. (When it arrived it was apparent how he could sell it so cheap as it looked like he bought Band Hero bundles on clearance somewhere and had stripped the drums out to sell separately.)
I know a lot of people swear by the GH3 guitar, but it was the worst one I ever owned and still dropped occasional notes even after I did the rubber band trick to secure the neck/body connection. The GH5 controller snaps tight and has been a great guitar so far.
Personally, I really liked the size and clickiness of the Frontman guitar and it can usually be had very cheap online. However, it is a pain to play with since the Sony firmware last year that broke a lot of USB peripherals. Since then, it a real hassle to get it to sync properly (usually a 5-10 minute process that only seems to work if I have it plugged into the 3rd or 4th USB port with ports 1 and 2 already taken). I don't know how much luck people with the newer 2 usb port PS3s have had getting it to work at all.
