Nothing wrong with Ryanair as long as you jump through the hoops. Indeed, they're quite useful for Tuscany as they fly from Stansted to Pisa and Bologna (the latter not being in Tuscany but still pretty close). Vueling fly from Gatwick to Florence. Easyjet from Gatwick to Pisa and Bologna.
As for bag charges, I normally just fly hand luggage only nowadays.
I have flown with Easyjet a lot. I know people moan about them but I have never had a problem. I only ever travel with hand luggage as it avoids a whole load of complications. 😎
I fly regularly with both Easyjet and Ryanair and I do not have a problem. Just get the right size suitcase, accept that it is just a mode of transport, you are not going to get pampered and that to get the good deals you are going to just be herded around. I prefer either of these two over British Airways - you just get a move on and they are rarely delayed at all. Just wear sensible shoes at the airport because you will be at a far away gate
