Need advice. Is $300 a good deal for a 41CV with manuals and 2 expansion cartridges?

Are you absolutely certain the seller is legitimate and really has these items to sell; have you seen photos of all the items, do you know him/her prior to this sale, etc.

If unsure, ask the seller to send you a photo of the 41CV displaying some number you tell him to show; this will guarantee the seller truly has the devices and is not simply using photos he found on eBay or reddit, etc.

Assuming all the items are present, and all items are in satisfactory or working condition (e.g. are both modules shown when doing a CAT 2) then IMHO yes, $300 is a fair price.

Good luck, and let us know how it turns out!
