Doubt if you will find a better price than this:
https://swasairsoft.co.uk/airsoft-guns/gg-combat-machine-aeg-cm16-raider
Add £5 for 2-tone & £8 for shipping
Then you have to still buy the battery/charger so you are looking at £155 say
But it is perhaps the safest go to option
Cyma's are OK, best bang for your buck if you are really on a tight budget
Yes motor is lame, it is a slow 28tpa motor - the G&G Raider's motor is not ultra fast either
(think your m8 had a lame motor, low battery on a 400fps Cyma if shooting 8rps)
They do a cheapo Raider clone CM517 which isn't bad if you are really strapped for cash
Yes they need a bit of work, but I have bought worse from JBBG in the past
G&G if you can afford it - if not a Cyma is not a bad gun really
The G&G is better - but then you are paying more
Should hold up well, last a good while & easy to sell on
