I bought a SMK Artemis P15 bullpup in .177 a couple of years back, it has a good shot count of over 100 on a fill, accurate and very light. I did however change the standard stock for a 3D printed stock made by Bob Pattenden, I think that's his surname? I also bought 2 x 3D printed magazines which hold 16 pellets to go with the 2 standard ones that came with it which hold 11 pellets. If you look around it may be possible to buy a second hand one for under £300.
