Welcome
I too collect mostly cheap stamps, and since about 400,000 of them are considered cheap or "pennyworth", you shouldn't have a problem.
I've found that obtaining my country's stamps isn't easier, because fewer private people use stamps, so it's less easy to get them from friends and family. My main source, therefore, is exchanging worldwide and cheap bargains online, like a German dealer I found on
ebay that offers 10,000 stamps, with duplicates, for 40 EU.
As for equipment, being a low-budget collector, I found I can get along with eyebrows tweezers, nail polish UV lamp, and so on.
Good luck.
