What's the best .50/1 site for a new player?

[Moneyline]

A relative of mine wants to start playing online poker recreationally at limits of .50/1 and 1/2. He wants me to recommend a site for him, but I haven't played those limits in so long that I'm not sure which site would be best for him. Below are the criteria (in no order) that he needs from a poker site.

1) The games at those limits must be soft enough so that a very tight, yet unskilled player can still expect to turn a profit.
2) The rake must not be prohibitive
3) Software and customer support must be decent, but they don't have to be the best.
4) There must be enough traffic, especially at peak hours and on weekends, so that he'll be able to find games to play
5) The software must not have easily accessible -EV casino games, side bets, or sportsbooks that might tempt him.

I'm thinking either Stars or UB would work, but I'm not sure about the game quality there. Anyone else have suggestions on what site might be good for my relative?

Thanks in advance...
