I can't / won't recommend one, but will suggest you have a look at the mags in the shops these days, see their reviews for (super)budget machines and then have a word with the manufacturer of a few that are reviewed there. You will be able to get them to customise it as you want.
Any machine on the market for about £800 incl. will do all that you have stated, should have a decent sound system and be upgradable when necessary.
