Certainly. Generally the Besson which have followed yours named 967 are the closest in terms of bell size. All modern euphoniums have what is technically a large bore (0.580"-0.590"). There are some notably oversized euphoniums but nobody buys them - Courtois being the obvious example. In short, if a euph has a 12" bell, it is a similar bore size to your instrument. Avoid 968 - large bore but an 11" bell. Also the rare 966 was medium bore and 11" bell. Avoid York because they're appallingly put together although the 3067 and 4052 are similar bore size. Besson Prestige 2052 is the same bore size, but 2051 is large bore with the smaller bell.
Regarding weight, almost any standard large bore euphonium; with the exception of the Sterling extra heavy bell and Besson Prestige models, will be lighter than the hooter you're currently playing.
It's been 3 years since I sold brass for a living but even then the phrase "emperor's new clothing" was applicable to euphonium design. Personally I wouldn't waste money on a new one unless you're in the position to be able to try multiple examples of a model you like - there is still too much disparity between them.
The last new euph I had was e German Besson Prestige - it went back three times under warranty in the course of a year. I might consider a Yamaha Neo - brilliant to play but wouldn't bother with anything else, although I admit the Sterling seems to have the done the best " round stamp" impersonation.
If I was in the market for a euphonium, these would be my criteria;
1) Post round badge Besson, either 966 or 967 (the ones immediately after the "Globe" with Besson stamped in the bell - same build but nylon valve guilds etc).
2) Round stamp Besson - but would have to be a good one as many I have played have been poor but when you play a good one...good grief!
3) Pre 1974 Imperial.
4) Used German Besson Prestige.
I hope this helps - I will also put up a photo of the Globe euphonium I'm currently playing - made in 1974 for Lyndon Baglin and is the first one, replete with gold plating and hand-engraved bell. It's too nice....
