in my opinion, markbass is way too expensive for just a practice amp at home.my SWR LA12 gave me a good boomy sound. its only 65 watts but at home, i doubt you'll need more than that. i bought mine used at GC for like $150.also i liked the sound i got out of the GK combo amps.
no more than 200 i spent the big money on my 4x10 and amp lol
this is what i'd get.http://www.guitarcenter.com/shop/product/buy_ibanez_sw65_65w_bass_amp?full_sku=480137 orhttp://www.guitarcenter.com/shop/product/Rocktron-Rampage-Bass-60-Combo-Amp?full_sku=480993The Ibanez above is super. I own the smaller 35watt 10inch speaker. A guy I work with has the Ibanez above. It thumps, the low end is great.
.....I scored a Crate 50-watt off Ebay for $80 shipped, and it has great sound. ....
for home i'll go with a fender 30watt rumble, or something like that, they sound good when turned at lower volumes.
