I work a great deal in IT, so tend to use their techniques in my own projects. One is called Prototyping" where they build a shell of a system, just enough to demo to the customer, then when the customer finally figures out what they want, throw away the prototype and build the real system.
In that pattern, I bought two PCP's in the past few years. A Marauder in .22 and learned a great deal about how PCP's work and what I want in the next gun. I then bought a Crosman 1701P and found out that as I age, and a bit of Muscular Dystrophy creeps in, heavy, front weighted pistols are just not where I'll be good. After converting to the carbine stock version (Which I really like), decided what I really want in my next gun. And I must admit having a top end FX doesn't hurt the ego any either.
So, I've also spent some money and time on guns that yes, work, but are stepping stones along the way. I will keep both for now, but may sell eventually. Also have 5 springers that led to PCP's. Same for scopes, have a bunch of cheap scopes, with two or three better scopes. Even still have a 40 year old Redfield Widefield (Steel tube, so heavy!) but it's got great glass.
I view it as a journey, just one I want to do as few dollar transactions as possible, being the consummate cheapskate.
It is a FUN JOURNEY though. If it wasn't fun, I wouldn't be here and the PEOPLE ARE GREAT!
anyway, gotta go to work so I can afford to pay for this thing.
