I have the D-Link 624. Its ok, but not the greatest (though its pretty cheap nowadays).
I too get dropped signals, but I've never had any problems where it needed constant resetting. I think a lot of it (dropped signals) has to do with where you put the router. Mine, unfortunatly, is in the corner of a room in my aptartment on the opposite side of where my office is.
