Ok,
I've actually just bought racing seats. And please listen to me:
You are gonna pay more buying cheap seats than buying more "expensive" seats - it's something called seat brackets!
If you get a pair of sparco's, it's gonna cost you somewhere around 600-800 i guess w/ seats and brackets that fit your car perfectly.
If you get a pair for $300, the material will be much crappier and you will have to either custom fabricate seat brackets ($300 or so) or get sparco brackets and modify them for a crappy fit.
I have Megan Racing seats right now about $450. The brackets are costing me about $200 (sparcos). I am hoping like mad that the MR seats will work good w/ these brackets.
The seats themselves are great quality tho, same as the tenzo's and sparco's I've tried.
If you want one for about $200, the material is not mesh fabric, it is cloth.
I've sat on some from a local supplier - $250-$300 shipped. Holds you in pretty decent, just the cloth material is not my style. And, you will have to do a lot of work to try to get seat brackets to fit.
Whether you get $200 seats or not, remember, seat brackets and fitting will also be a big concern.
Considering the seats are one of the most consistent things you will be using, you should seriously consider getting a decent pair. Just save up. Or only get a driver's side, who cares about your passenger, hahahaha.
Here's the NexTech seat I tried that fit me pretty good (I'm 5'10" 175lbs):

If you are in the South Cali area, I'm sure he'll give it to you for $200 local pickup. Just tell him (James) that Quoc-Viet (pronounced Kwa-Vet) with the 240sx referred you.
He's a very nice guy and can get you good seats too.
I'll let you guys know if there is much modification needed to the brackets for it to fit the 240 good once I install it next week.
