First of all, thank you for the helpful reply! You are just the guy I was hoping that would respond, seeing that you do the storage reviews on HWC ;-)
So, basically, the C300 looks most promising for my silly mobo, considering the unmovable budget limit.
The mushkin, available at newegg, I was previously thinking about as well, but since ncix doesn't have them (yet), there would be additional shipping costs. (I like to pick up in store, because I am a cheap bastard

)
Now, seeing a few threads in various forums, there is talk about new generation ssd's coming out from several manufacturers in march, so maybe I should wait a bit longer and see.
Hm, so either the C300 or the corsair force (which I could pick up tomorrow) or wait a month.
I think I am going to finish my bottle of absinth and then make a decision.
Sounds reasonable, no?
