Dude, don't make the same mistake I did. I first bought a 120-watt Line 6 amp thinking it was good enough for playing at home but, sh*t, that thing was too powerful and loud!
I ended up selling it and bought myself a 15-watt Marshall amp. I dig my new amp and it's loud enough to play at home.
Anyway, my bro has a 15 watt Fender amp which I borrowed once, and it's a decent amp for less than $100. My suggestion is that if you're not going to do gigs anytime soon, then get a 15-25 watter but no more than that.
