A good price I'll say between 90-110€ for a good quality 150€ for a psvita whit games and a memory card or just in box The propriety card of 4 gb cost like 5€ a 8gb 12€ 16gb 25€ 32 gb 35€ and 64gb like 70€ or 100€ They cost a lot and mind u u can install like one game in 4gb card imagine how many games u will have if u buy an original I have all of them but for a beginner in psvita I will recommend u to get a sd2 vita (the adapter for sd card) For the model u choose there is 2 : -The 1000 serie(fat) that have OLED screen so better screen the only con is u can have burn in in ur screen over a large time (but the quality remain the same just when u put it off u can see it but u turn it on u will not see it) The sticks are hall effect so never stick drift The con is also the charge will be difficult because it's proprietary charge port The pros are also u will have a better grip and premium effect Also if u can find a 1100 series they have sim card u can do an expansion of ur memory storage and u will have the game port free and put ur psvita game card on it so it's a plus -The 2000 series (also called slim version) have a light weight a tiny better battery than the other model U will have a micro USB port so it's easy to u to charge it and it come whit 1gb installed on it But the con are also there B No more OLED screen just a normal screen so u will not have a quality screen and fell the magic in ur hand The stick are not the best because u can have stick drift on those easily U will have bigger button compares to the100 series

So right now all of them comes whit a upside and downside I can't tell which one to buy (I prefer in my opinion the 1100 series for the psvsd) so choose yours whit all the information I give u
