I have a Beseler 23C II and I love it. I actually bought it on ebay with a ton of stuff (focuser, trays, lenses, etc.) for about a third of what you stated there. Granted, mine was used, but it was not abused! I was able to find a manual for it online (free) and it has served me well.
I think if you have to crank the head up really high for any enlarger, you'd want to anchor it to a wall or something. But I've not had a problem with mine. The enlarger head can tip 90deg. to project to a wall if you are enlarging to poster size.
I definitely agree with Ann that you should look about for a better price.
