Spirograph recommendations

[RunAwayTurnAwayRunAwayTurnAway]

Vague memories of loving my Spirograph and I want to buy one for my DS7.

There are so many options - travel, junior, deluxe…

Can you recommend the best one?

Also, which pens work with them? I think it used to work with slim felt tips?

When I was a kid, long, long ago, I had an ordinary spirograph set which was just circles. Later I won a superspirograph set. It used shapes other than circles and was significantly more fun, but also harder to do. IIRC we used cheapo biros.
