But to answer your question, probably not, you need a 2.71 PSP or lower to be able to downgrade, and to get to v1.5 you can't have a TA-082 or TA-086 motherbaord, which I believe most new PSP's have now.
You can always get one off of eBay, is where I have bought all of my PSP's
I think it is possible to play backup games in v1.5 and in v2.71 by using a Dark_AleX's HEN D + DevHook

If I buy a new PSP, can I always downgrade it to v.1.5?
Is it just in v1.5 i can play backup games, isn't it possible at all with any other versions?
no you cant always downgrade ,see this thread to see if your motherboard is ta-082 if it is you cant downgrade to 1.5 if you try you will brick the psp
