I get bored easily with guns. I will keep one for a few months then sell it off.
I have less than 5 guns that I have had for more than 5 years.
I have a hard time getting rid of my guns. I have sold a couple in the past, but only to put towards the purchase of a new gun. I would never part with any of mine for any other reason. Many people regret selling their guns, but if it makes you happy go for it. I think if you are selling some to get money for another you will be fine. You said you were selling a few of your cheaper ones, so at least if you happen to regret getting rid of one of them you could pick it back up fairly easy. Good luck with your decision.
