Okay... so we have all the Xeno E03 votes. I'd go for that, too, but aren't we choosing from something they already stock or are a dealer for? They don't appear to be a dealer for Xeno.
You guys really gonna waste your time TRY to get a group buy on a $7 item? Just to save a buck or 2 to me it's not practical. You can get cheap light on ebay any day. Sometimes with coupon and some good find you can do better. I paid $47 for my Sunwayman V10A ( i use 10 off 50 coupon instead of summer coupon) ,now that's a group buy.
IMHO, good group buy is at least 20% discounted the lowest price anywhere else.
quite agree with tim817, tk 45 which is usually more costly than tk35, now cost around $90 at DD after 20% off.is cheaper than tk35. now i m really caught between this 2.
