Lets exclude woodwork items as I suspect we all collect those a bit.
I have 2 things
1/ started to collect vintage pedal cars, had to stop at 3, as pandemic just drove prices through the roof. Still look but need prices to drop a bit.
2/ Viz comics, easy to get hold of the majority, still find them very funny, I have about 290 of the 310 issues. Some of the early issues are rare and pricey so whether I'll get the lot is dubious as I can't see me doing a grand on a comic, so far it's cost me £270 total.
How about you?
