i recommend the DIY method. There are plenty of good tutorials available online.
i have opened up my decks and replaced the RCA & ground cables with a buddy of mine, really was not that difficult at all.
If you need to flip your table over, just make sure to place it on a pillow so that no damage is done to the tone arm.
What is wrong with your deck? Maybe i can help ya find some info to repair it yourself. PM me if you need to just post it here as other may also find it useful.
