Nearly all pairs will do the job. Cheap pair will be fine if you are sharing them around - check hand size though. I play all year round on astro so usually get a pair with a bit of finger protection, cheapest brands go for around £30. pair usually last me a year playing twice a week.
Plenty of cheap pairs on Amazon: http://https://www.amazon.co.uk/s/ref=nb_sb_noss?url=search-alias%3Dsports&field-keywords=goalkeeper+gloves&rh=n%3A318949011%2Ck%3Agoalkeeper+gloves
