Opinions please

 I'm about 2 weeks away from ordering a new pc from adk. I've been using my Line 6 hd500 as an interface but would like to free it up. Adk suggested the Presonus 22vsl (they said it has lower latency than the others in that price range). I'm also thinking I'll get Sonar X1 studio. ( I bought MC6 awhile back and really like the flow) My question is....Should I get the 22vsl or something else? I've looked at the Focusrite scarlett 2i2. Sweetwater says my hd500 will sound as good as either one and I should wait untill I can afford a RME. 2 inputs will be enough for me...I like to work alone. What do you think?
