I've read some good things about SX (some call them Essex) basses on both the "Ho Bass" section of "The Dudepit" and on TalkBass dot com. Everybody seems to think they are pretty solid basses for the price. Most folks put them head and shoulders above comparably-priced instruments like the Squier and Rogue basses. That's why I am considering taking the plunge, sight unseen, although now I am thinking of getting a fretless from them.
BTW, one of the owners of Rondo Music monitors and posts on the TalkBass forum.
