My thoughts about the T61A - (not the ex-RAF animal).
45hp that is usually sufficient.
Great fun to fly, much under-rated.
Economical, easy to maintain.
I believe it is now
possible to operate on a Permit to Fly (LAA)
Best of both worlds - with and without power. Many will say it's the worst. They often have no idea.
The downside, especially these days, is a bl..dy great wingspan needing hangarage.
That wingspan and limited power does preclude use of small strips.
Slow cruise not always so good for flying in company.
As an eightish stone weakling (then) I didn't feel lifting the tail was beyond me, just something not to be done more than absolutely necessary.
Overall, I'd say if the cons aren't a major issue for you, it's a no-brainer. The glide ratio isn't up to much if you look at performance in gliders but not
that bad and far better than most of the aircraft found at the local airfield (Lasham etc excepted, of course).
The fun of all that cheap -or free - flying is hard to beat. Try it!
