I had a look at at the Creation Station. I'm sure it'll meet your needs, but it's expensive (there goes the OP's under-$1000 requirement). And there's a certain amount of smoke-and-mirrors in their marketing: Some of their "special features" incude "audio-grade RAM" and fans to "prevent dangerous heat buildup."
Rex, you have a point with regards to slick marketing and special features.
However, the creation station is perfect for a person such as the OP who doesn't know much about computers that wants to record using a "fairly strong PC".
My experience with Sweetwater and purchasing the creation station was fantastic.
The difference with the OP and myself is I know computers.
I've built my own for years. But at the end of the day, the creation station came with all the hardware I needed, all my software installed/registered/configured (including software using a dongle), plus all the very helpful tech support in case I needed assistance.
Just saying.
Yes, the price is higher than the OP needs.
However, frustration pay for do it yourself PC builds and all the headaches of tweeking & tweezing a PC with little experience adds up.
I purchased a creation station & a presonus a/d interface about a year or so before I purchased an AxeFx.
Both have been rock solid performers.
Well worth the few extra $ for the OP's budget, with ease of mind everything works well together.
