You can basically get any deck you want, the only technical things you gotta be concerned with is getting the correct harness and dash kit.. If you bought a new deck on say crutchfield.com, I believe they throw in the install gear, but you're spending over $100, ya kno? I went with a used deck on ebay for less than $20 lol, but it works fine and has all the features I want like mp3, aux input on the front, cdplayer, etc.. and I also got the harness/dash kit on there too for about $20 total.. That stuff would run probably about double in a store, but it just depends on what you're looking to spend.. If you bought everything new, you'd probably be looking at at least $300 for a new deck, sub, amp, accessories, and then possibly more depending on if you install it yourself.. But you can definitely score stuff cheap on ebay or craigslist, trust me.. There is the possibility that you get unlucky and it ends up crapping out, but it's not something I was really worried about.. I've honestly never personally seen a deck, amp, or speaker break from normal use.. I have receivers and speakers that are like 20 yrs old that still pump.
