If your looking at packages eg warped sports do ones including the Gtek 170r or the Geo4 I’d ring and say you want x goggles and x tank see if they will play with the price to get you the kit your after.
Failing that’d get a decent set of goggles then I’d search the BST pages of Facebook or even the sales threads on here for a second hand marker that you’d like most PE markers and great and can get a 170 for around £450 or a cs1 for about £400!
