Advice needed Please, To Fix Or Not To Fix?


My AV receiver needs repairs totalling 317 bucks. This includes the 60 bucks diagnostic fee and tax. The repair man tells me it needs a new output board, multiple caps are leaking, and there is signal loss all over. He will also thoroughly clean it up inside. A complete referbish as he puts it. It's a Integra DTR 5.4 and I have had it for years. I always thought it sounded good. I have it paired with a combo of Energy and Yamaha speakers, sub is Energy too. What do you guys think? Worth fixing or should I get a new piece? I really miss not having 5.1 and want the sound back but I do not want to spend too much on a new piece. What would I have to spend new or used to at least match this piece? Thanks in advance to any one who responds.
P.S. The price quoted for repair sounds pretty fair, but I admit to not having too many things fixed so I don't really know.

Paraneer and all the other guys that responded, thank you for the advice and honesty. I will get a new piece. I was using it for movie playback only (Whatever I buy will be used the same way, I have a separate two channel rig for music only) and have been more than leaning towards getting something new since it went down. Thanks again everyone for responding.
I'm an Onkyo/Integra fan. I use Integra AVRs in my Home Theater Room and in a much smaller, video-centric set-up in my family room. I also use an Onkyo Pre-Pro in my more elaborate two-channel system because I'm hooked on room correction.

The Onkyo TX-NR 709 is available at <$550 from big box discounters and it features full-range Audyssey EQ (including the critical subwoofer correction). If you have more to spend, you might look for something from a premium brand, but the 709 is an excellent option for the +/- $200 premium vs. repairing your existing AVR.
Marty, thanks for that input. So is Best Buy where I can find it should I choose?
I got the price with a quick Google search. I don't recall exactly which store had it listed for $549. My guess is that if you find one, any other will match it, so Google on!

Marty, Amazon has it listed for 499.00! Here is a dumb question. My Integra was 5.1, this is 7 channels. Do I need to get more speakers? Can I just hook up my previous gear and be cool? Sorry I must sound ike an idiot.
