I have 2 Excalibers: a 110 and a 75. Both have served me well for many years with very little maintenance (a little WD40 in the trigger every few dives) and no failures or misfires. It has a frictionless trigger and line release which is really nice, and it's very accurate. However, don't beef up the bands too much or you'll wear down the seer.
I also have a T20, but it has misfired a few times when brand new so I don't trust it or use it anymore.
I also know that the line release on the Caymans sometimes get stuck, and need to be reset with a small screwdriver. This needs to be done back on shore and could spoil a good dive (note: always carry a backup gun on your float). Not every Cayman has this defect, but it would suck if the one you buy does. Also, HFs and HF2s are expensive.
I recommend the excaliber. I have 2 and my friends have 3, and we all love them.
