The 373 is the entry model and is pretty stripped of features so you are looking at barebones basic model. It is also the only model out of the x73 series that uses IC chip amps instead of discrete amps, and it will not be as powerful as your old Pioneer. Unless you are trying to drive low efficiency speakers in a large space, it probably won't matter too much as it takes a doubling of power just to gain 3 dB's. Lack of features may be a disappointment coming from the Pioneer. (of course if it still does everything you need, why spend more?) I myself would look at the next model up, the 473, but it sounds like current street prices may be a bit high for you if your budget is only $250. If you are looking at saving money, you could also go for like a refurb Denon 1612 at Accessories4less. It will still come with a 1 year warranty. Check out the official Denon xx12 thread for more info. Again, you need to decide what features are important to you to sort of guide your decision. Older refurb models are often great ways to save money on a high quality product if they have the features you want. You can often get a lot more receiver for the money that way.
