Thanks, guys, for the input. I had also emailed Happ and they gave the same advice--although the Toshiba 27a34 (or 27a33) is almost flat, they still suggest the standard rounded bezel (part # 49-0106-00).
FYI, beware the shipping cost from Happ. All I purchased was the bezel and some marquee retainer and shipping is just over $40. They don't tell you ahead of time (during the checkout process) either--you go through and confirm the order and they tell you the shipping cost later once its shipped.
Had I known it was going to be this painful cost-wise, I would've just made my own or kept looking locally.
