Heck, you could even get a TLA 280 for $19 at KEH. It has bounce, a zoom head (manual zoom, but still) and even has a secondary fill-flash head and second-curtain sync capability. It's similar in size and weight to the TLA 30. I recently got one for my RTS III. While I doubt the SB600 would fry the electronics of the G2 (iirc, the SB600 is meant for use on digital cameras as well as film, so it probably has a lower trigger voltage), it would NOT be TTL with the G2 - you'd have a manual flash with it. May as well shoot a Vivitar 283 at that point. Which isn't a half-bad option because of the power a 283 packs.
