Red-dot finder suggestions?

I'm looking for a unit-power finder for my WO Zenithstar 80 than I can also use in the daytime. I want something small that I fit in the case, perhaps in a 2" eyepiece hole (the hole is deep).

The scope has just a single screw mount point for the finder; aside from the WO unit (which is out of stock) and Rigel (which probably doesn't work in the daytime and might need to be placed further down the tube), most of the finder mounts have two or more screws, or aren't curved, or don't have a quick-release, or something. I'm not anxious to use tape. I wish finder mounts were more universal. I assume they're all similar and maybe something would fit in a WO base, but I can't tell from the pictures. Any suggestions? Thanks very much.

Burgess Optical sells the exact same finder as WO. They do not have the elevated mount that WO has, but the Burgess finder fits the WO mount.
Excellent unit!

I have the Stellarvue version of the WO finder. Great finder but the red-dot is not very visible during the daylight even when cranked up to full brightness.

I've been using the Orion EZ Finder on my WO80FL and the dot on this finder is easily visible during the day. The dovetail base that attaches to the finder can be mounted using the single screw hole on the scope's rotatable focuser. You just need to get a metric flat head screw that's the same size as the set screw on the scope (M4 ?) and slightly ream out one of the holes on the plastic dovtail base. The single screw holds base very firmly with no movement. This is a quick release unit and is small enough to fit in the case.

Good luck!
