My car needs some TLC

I've been having some issues with the cooling system on my car for several years. In the last few years I have replaced the radiator, the upper and lower hoses, the cooling fan, the temp. sensor for the fan, and the thermostat. It still uses coolant, but doesn't overheat or act up much because I check the coolant level regularly. I recently came to the conclusion that I had been purposely ignoring for a very long time. I probably need a new head gasket and some machine work done to the head. I found a repair place that seems to be very highly regarded with good reviews and went there today to get an estimate. The place looked kind of sketchy and a little chaotic when I got there, but I went in and talked to the owner. I think I may have come to the right place. He seemed very knowledgeable and helpful. He gave me a rough estimate of the charges and I was really surprised. If the head gasket is the problem and there are no other issues, he will charge about $500 to replace the gasket, get the head machined, and replace the timing belt. I was surprised and was expecting a lot more than that. I thought it might be time to sell the Harley so I could fix the Honda. How ironic would that be? Although I still might sell it. I think I'm getting closer to that point. Anyway, I made an appointment for next Monday and if all goes well, it will be ready by Thursday. If not, I could be car-less over Christmas weekend. I'm not all that worried about it though. No school, no work, there is the bus and MAX if I need it. Hopefully, after this is done, my car should be ready to go for a long time to come. It has nearly 200,000 miles on it now and should have a lot more left in it with a new head gasket and timing belt. Expenses like this suck, but since I was expecting it to cost a LOT more I'm not letting it bother me.
