I'll tell you what ever heard
"You get what you pay for"

go ahead and buy those crappy ebay bars that are hollow and weak as all hell. You won't stiffen your suspension at all, you'll just be adding weight.

Think I'm kidding ask anyone with those cheap ass bars to lay it on the ground and stand in the middle. The watch in amazment as it bends/flexes...or even breaks.

Try that with a Neuspeed/Spoon bar and you'll get no flex or bend at all. There are some things you can skimp on. but don't do it on your suspension.

If your driving a prelude you already have one of the best handeling cars honda made... try and improve upon that...not make it worse
