As annoying as it is as you've already spent your money on it, it's probably best to just write it off and buy a TM. WE Hi crappas are notorious for being one of the worst models WE have put out. Trying to sort it would most likely result in throwing money down the toilet.
I've used them before. Some confusion with OOS items and sending the wrong stuff but got there in the end. If they were the only place that had something I wanted, I'd be OK with ordering from them.
I see you've short listed two pretty impractical pistols so let's move on from practicality. My vote is the TM Desert Eagle. Silly, silly pistol but a lot of fun.
These Chinese Eotech clones have been around for a while and are indeed holographic. I believe this one is a rebranded Lindu Optics one at around the inflated cost of a sample.
A small order puts them at £280 each. I think at sub £250 they could be interesting.
The ad is a bit old but the seller seems active still. Have you tried this seller?

Yeah. The ebay price did surprise me. I think the main issue with these is that whilst they're advertised as 75 rounders, they can take considerably more so unless you're careful about loading, you can run into issues. Stay at 75 or thereabouts and they're fine.
I have 10 x Magpul PTS licensed Beta Project FDE midcap 75rounder Pmags I am looking to move on. They are very slightly used. Rub marks from mag well if you catch in the right light etc.
Long discontinued now. I saw a new box of 5 sell on US ebay for $90 shipped so £73. £73x2= 146 x 0.75 = 109.50. So is £110 posted fair for these do we think? Difficult to get other prices as they're not all that common now.
Shooting from windows was a bit of sore point when I played Gangsta City. Default rule for most sites I believe is don't open/close any windows or doors (some sites just windows). Leave them in the state you find them. Though I'm sure this was skipped in the brief as they assumed everyone was familiar with general rules. First mistake.
Then people started abusing windows. Opening them, shooting from them and then closing. Then they decided to change the rules mid game that you weren't allowed to shoot from any windows. Second mistake as that news didn't get around to everyone causing some people to be lit up from windows who hadn't heard about the rule change. I'm pretty sure the rules changed one more time during the event but I could be wrong.
Surely mil smokes are banned at most sites though? I'm pretty sure every brief I've heard specifically includes no mil smokes. EG claim to have non toxic smokes.
