I strongly recommend you get a front-loading washer. It will not have the mega-capacity you want, but 1) it is gentler on your clothes, so they last longer, and 2) it is more economical of water, so your water bill will go down. It will cost you more up front (probably around $800+), but the payoff in clothes and utility bills is worth it in the long run.

We got ours from Sears (a Kenmore (what else?)), and so far have had no problems with it after five years.
