Hey fellow Czech person

Can't offer an AIO kit but if you'd be willing to get all of the components yourself, I can put together a list of distributors/auctions I used for my build. Would you be interested in that?
I don't know the price of the components altogether but I think I'm just above 5000 CZK (200 USD) right now while a colleague of mine who's skipping the entire cartridge reader bit is at around 4500 CZK (180 USD) last time we checked.
Edit: actually
compiled the list just now, it includes links to Czech distributors and some notes that Czechs might find hopefully useful. You can get the price further down by getting rid of the cartridge part and by not using Adafruit components, but I wanted to have a build as close to wermy's as possible. Finally, as noted in the list, I might have a 3.5" display for sale soon, maybe.
