Directron sells Sonatas w/o a PS. It's not much of a savings though, $99 vs. $87--not worth it in my opinion. They do also sell the slk3700ambs w/o a PS-- $69 vs. $49. The 3700 is a better deal, but I'm leaning towards the Sonata w/ PS.
I can't comment on shipping or service as I haven't dealt w/ Directron before.
Got my case from them. No damage. Reasonable shipping time. I did have to RMA some other parts (because I changed my mind, not because they were broken) and it took a bit of time (I think over a week past the receipt of the returned parts) for the credit to show up on my card, but I think that's normal for any non-newegg.com online store.
