I know the HX series is pretty common but I was reading thier website and the HE series seems quite cool. They have the option of somethign called VGT which if you read up on thier site its like it adjusts the A/R ratio almost to suite the situation automatically also has water cooled bearing housings among some other stuff Ive never seen or atleast hear of on the HX series. Now the HX55 apperently has the VGT option but Ive never heard of one with it. I was thinking about 2 HE200's which are somewhere in between the HX27 and the HX35 as far as size goes... anyone know anything about them other than what Ive said mainly has anyone used or know anyone that has used them?
