miscellleanous airgun queries

[andy_65_in]

Hi am ken to acquire through my USA based bro one of the three airguns viz BSA Lonestar,FX Typhoon or Air Arms S 400 EBR in .22 calwhich are the cheapest entry level PCPs less chinese copies.which one is better, im banking on the bsa being the cheapest at $ 595 with fixed iron sight.also is there any jugad to reduce noise levels of such PCPs like a moderator etc,i think superior models of FX do come in shrouded barrel versions.also what air filling system cn one manage here if one doesnt get the air pump with the airgun from USA.can you mange a scuba tank as suggetsed by someone or can a local cycle pump suffice.my bro tells me even the bsa screams louder than my brno .22 rimfire!thanks andy
