Personally I'd go for a 152 as it's a lot cheaper. You can convert to a PA28 after learning in about 2 hours - this can save you as much as £1000 over the course.
^^^ Me too mate, from a fiscal point of view that approach made total sense. I endured the wrath of a very cosy C152 cockpit (at one point was sharing this confined space with a tall 6'5 instructor in crappy weather doing windy circuits

) for the better part of ~50 hours during my PPL training. Decided to checkout on every SEP that my school had to offer after though as I needed something roomier to accommodate PAX & those lengthy Nav exes that you will need to be doing in order to fatten up the log book post PPL
Hope the lesson was a good one today ? & by good I mean you remained feeling puke free throughout your hour? I remember my first lesson ever was quite scary in the sense of serious self doubt i.e basically, the instructor who took me up was very 'WWF' like in his handling/ controls input in the flimsy C152....as a result I was naturally left in a sickly state when we landed. From there I naturally began to seriously question my ability to learn to fly & kept thinking how long till I bloody get 'accustomed' to the rougness of flight training

Turns out I wasn't the only one who couldn't 'stomach' his flying & things felt/got much smoother after (did my first 6-8 hours with him) his absence from the RHS
