Hi, and welcome to Beoworld!!
The 7700 you're looking at is a good all-in-one system with plenty of oomph. It produces a good sound and can be used by remote. You can also create a multi room system with it ie have speakers in another room.
The MMC4 stylus is not the best, but at least it's not an MMC5!
I must confess I don't know much about the speakers, but you should be able to refoam them. If you pay someone to do this it can be costly!
I would think the price is a little on the high side, but not stupidly so. If you want to get the most out of the 7700, you'll want to utilise all it can offer (see link below)
Good Luck!!!!
