off the top of my head, a few good bang for buck companies are scorpion for helmets,
go to the dealer to try things on in person if possible. and from my experience, aftering wearing leather, textile feels extremely inferior fit and protection wise. there are still times i wear my textile jacket
As for a helmet, I use Scorpion and they fit and feel amazing IMO.
On a side note: if new isn't a big deal to you, you can find good deals on Craigslist on jackets and gloves. Although I wouldn't buy a used helmet.
+1 on Scorpion; they saved my head once. Stay away from used helmets. You don't know what has happened to it nor how it has been treated. If they always left it sitting on top of the tank, gas fumes may have weakened it. If it has been dropped, there's the potential for damage (helmets are one-time use devices; if you're in a crash, destroy it and toss it. You're not supposed
to use it if it drops from a height, either).
As for what Glocken said, maybe it's just my jacket's sizing, but textile just doesn't fit right; I don't like how it's baggy. I'm getting a leather one for Christmas. Again, look at discounted items online and go through the reviews for it.
Don't completely avoid non-Snell approved helmets. There's research out there showing Snell-approved helmets can sometimes cause more harm than good. A helmet's purpose is to prevent the brain from slamming into the side of the skull (along from keeping the skull from being crushed); the helmet's shell cracks and the foam crunches to slow it down.
With some Snell-approved helmets, the helmet's so strong that the shell won't crack. Snell helmets are strong because, from what I remember, they're tested to withstand two impacts as opposed to one for the DOT-approved ones.
The Scorpion EXO-400 is not Snell-approved and I trust it completely. Go with a quality helmet, and you'll be fine.
