I am offering a real simple choice that fits your budget and easy to find. I wanted enough power to play with buds in the garage, with the ease of a practice amp as I just started playing and do not want to keep buying up. My budget was to try to stay under $250. I am very happy with my new amp.
I just bought the Ampeg BA112v2 from the Ampeg eBay store. It is a B stock, the issue being a 3 inch scratch on the back top edge of the cabinet that you can't see from the front, and is hard to see when you know where it is. The cabinet feels very solid, the lift handle is strong, and at under 40 pounds, it's easy to move. It's rated at 75w @ 4 ohms, has the adjustable overdrive, high/mid/low tone settings and "ultra high/low tone shaping" switches for a lot of tone shaping possibilities, inputs to add another cabinet, a footswitch, headphones, plays mp3/I phone with its own volume so you can play along or just listen, integrated DI and more. I got it shipped to my door three days after I bought it, total price was $189, new off the floor they are over $300.
I'm sure you could do better if you spend a lot of time constantly rechecking every site there is for a deal on something as I did until I found mine. But mine was "new", warranteed, and is sitting in my living room waiting to be played, right now. If you have only one amp, I think this is a real good option.
