Would like to buy one.
If you've never owned an Amiga, you should be looking at Amiga 500 (most sold, most modern expansions, highest direct software compatibility).
Otherwise, get a miSTer and use minimig-miSTer core.
1000 being the first Amiga, there are a lot of limitations and annoyances relative to newer models. The 512KB maximum CHIP RAM is particularly crippling.
