you can do a search and check on different guns or just browse and learn.
I would suggest checking into a B20 or B21 personally. B20 is Break barrel copy of Beeman R9 and the B21 is a copy of the side cocking RWS 48. I am going to personally pick up a B21 in .22 cal for myself for just over $100.
I have an RWS 34 and it is a good entry level gun; you can get them in .177, .20, and .22 calibers for around $200.
