I too would vote for fixing it since it is a nice piece of gear. On caveat though is that I myself have shyed away from Onkyo/Integra because of their flaky hdmi boards. I have myself been eyeing a separate pre/pro and looked at Integra but I found many cases of failed HDMI boards with them on the internet. I am now saving my pennies in hopes of finding a Marantz AV8801 with Multi EQ XT32 I can afford/justify. Still if you can fix it for 250 you will likely get top dollar for it.
A few months ago, I purchased the new Pre-Pro from Yamaha, CX-A5000 and I compared it the Marantz 8801, ultimately picking the Yamaha because like you, I have owned Yamaha stuff before, liked it alot and in this comparison specifically with comparable features it was overall a significantly better value for the money AND a full FOUR year warranty.
