MB---I noticed you had this OB hive posted on your web site. Do you particularly like this one or are you saying one of your favorite things is an observation hive.
I have been shopping around and have looked at different ones. One I almost got was from dadant @ $95 but it utilized a medium frame @ which I don't use. I guess it could be retro fitted by the handy but probably not I.
I thought @ $135 the Ulster hive was right pricey. But as I said I am not handy and I guess you take what you can get---@ least most of the time
