I'm more of a "get better stuff second hand for the same money" kind of guy, but these packages are pretty good value for what are respectable guns for the money. Yes, you will get better quality form others, but if you want new with a guarantee and something to get you going you can do worse. Throw in the fact they can deliver and your going to struggle tp get a better deal. I personally would sell the hand pump for what you can get for it and buy a second hand 7L dive cylinder and whip for about £120 - pump filling a PCP is hard work, for the difference in money a cylinder makes a massive difference, but it's your call.

Calibre is always a tricky one, but I'd go .177 for most things with the exception of close range ratting which a .22 is devastating at - there is obviously no right or wrong here, just personal preference, but a .177 will most likely be easier to sell in the future as it has a bigger following if you just play the numbers game
