Another thought:
Since you'll be recording, you don't need to get high wattage - 12 watts or less will do. Here's some ideas that you could get to have a great collection and stay under a reasonable budget:
Fender Champ - doesn't matter Blackface or silverface, they didn't change this amp when CBS bought it. With a mic, sounds Fender great.
Reeves Custom 6 - 6 watt monster. Handwired, amazing tone.
Reeves Amplification Custom 6 and Custom 12 These are going for around $500 on eBay:
Reeves Custom 6 Hiwatt Marshall Plexi - eBay (item 180446493363 end time Dec-17-09 22:19:56 PST)
Dr. Z Mini Z - again, great amp with slightly different flavors. Handwired, amazing tone.
Mini-Z -- Dr. Z Amplification
Buy a good quality 1x12 speaker cab and get a quality Celestion or weber in there, and you've got multiple tonal options.
good luck!
