look on Ebay for Tektronix 22xx series scopes. Got a 2236 (100MHz) for $100 (with free shipping) and works like a top.
You can get one for 1/3rd the price, with 3x the bandwidth, and 2x the number of channels (4ch vs. 2ch) vs. the Rigol.
Slightly off topic perhaps, I have a 50 MHz tektronix which has served me well for years.I need a 300 MHz occasionally but would particularly like something that would allow a screen capture to a pc or stick, any suggestions please ?.

usually handle 1-100mhz (careful, some are in the khz range)
Quoteusually handle 1-100mhz (careful, some are in the khz range) kiloHertz would still be a million times better than milliHertz
I think you can get them at surplus stores.
