Getting back to the original point about a good place to start.
Like Mr Driver, I was lucky enough to start on a McCann (Another Duet)
and have never looked back.
Nowadays, you might find the odd McCann, but Cran Duets are as rare as Hens teeth. So, realistically all a beginner will find are English or Anglo systems. Both have their good and bad points.
If you want to play fast free flowing tunes, then English, to play a more rhythmic dancey/Irish style then probably Anglo.
Please don't shoot me, I'm generalising!!!!

Neither is really suited for playing big classical arrangements (Stop Firing Damn You!)

Good Luck anyway

(Psssst...Hang out for a Duet IMHO!)
