Bell RS-1 with transition shield. Look for older graphics to get it for about $200, then add the shield. This has a great double neck roll, high quality material, transition shield is probably the greatest single thing I have every seen on a helmet - game changer for me. It has nice large pockets in the ear area to add speakers, etc. Removable liner. Very nice ventilation and still quiet (relative sense see reviews).
To top it off you can buy the breathbox/winter conversion double shield for a decent price for winter/rain.
I have been exceptionally happy with this helmet and have installed speakers...if anything almost too much space since I had to use both pads to get the speakers next to my ear. Also has very easy to remove cheek and upper liners, you can get different thickness cheek pads to get the fit where you want it. Also has the best shield removal / attach I've ever seen.
I tried out RF-1200, have a scorpion EX700 and a few others. Only think I liked better on the RF1200 was that it was a bit lighter.
Only real con I have on the RS-1 is that the seal on the standard (non winter) shields isn't quite perfect. I still use it during western Washington winters, but once and awhile I get an internal side of shield dribble.
