With two exceptions, I wouldn't change anything.
1. I would not have purchased quite as much .22 long rifle ammunition as I did during the ammunition drought. No worries, it'll get shot, but probably could have better spent the $100 on pellets instead.
2. I would not have purchased any pistol. I purchased the 1701P, which to its credit is a great gun, but I just don't shoot pistol. Thought I would, but turns out I really like long guns.
The Marauder l purchased is a great educational gun. I now understand much better the relationships between all the adjustments, pellet weight and accuracy. Many consider it entry level PCP, but it's a great hunting gun. Tough, accurate to 50 or 75 yards, and has enough power to make the kill. Inexpensive enough you don't mind scratching the synthetic stock, unlike a FX or Daystate, or something else on the high end.
After a couple years of shooting the Marauder, yes, I will be moving up in the world, but the Marauder was the gun I learned on and I'll always love the gun. Probably never get rid of it either. Good stuff that.
