If you think it'll be a little while before you get into HPDEs, then I would recommend just getting the cheapest helmet you can for auto-x. I started out with an open face HJC motorcycle helmet (Snell M rating) that I bought for $65 or something like that. Looking at HJC's site, it looked like an HJC CS-5N, although that one appears to only be DOT approved (not Snell).
I now have an HJC AR-10 (Snell SA rating) and have been very happy with it.
'89 GT convertible, N/A 357W, MM front susp w/425# coil-overs and Koni D/As, MM TA/PB rear setup (Koni Yellows, 390-430# springs), Stoptech 332mm / 12" Baers, MM 6 point rollbar, Maier 1.5" flared fenders & quarters, 18x9.5" front/18x10.5" rear Enkei RPF-1s (street), 18x10" CCW C-10s (track), etc...
