Hi Kirsty, sorry to hear that you had a bad experience. CYMA is actually a decent brand and their metal gearboxed guns are noted for being robust (although the outer plastic on their M4s feels pretty nasty): it's a shame that they also make those £40 market-stall specials with plastic internals that really are disposable toys.
I'll keep it simple, PatrolBase is a reputable retailer and anything they sell will work. All the sites with "BB" in the name sell a bunch of tat (as well as some decent stuff, but you have to know what you're after). Stock levels are quite low at the moment, so there's not a huge amount of choice. One issue is that most electric rifles
don't come with a battery or charger, and even the very cheapest charger plus a nimh battery will run you £25. The cheap CYMAs
do tend to come with a battery and a very basic charger with a 2 prong EU style pin, although it's never guaranteed: they're treated as a sort of bonus free gift by retailers.
Any of these will do:

Annoyingly, you can't filter by whether they have an included battery, you'll have to check the description under "Included Items", and even then you'll find contradictions. The Lancer Tactical M933
says that it does, but I'm doubtful.
If you do need to add a battery and charger, then these will work for £25.

https://www.patrolbase.co.uk/vp-racing-9-6v-1600-crane-stock-battery (this will fit any of the M4s, but not the G36s or AKs)
I certainly wouldn't
recommend them, but you'd be looking at £45+ for the very cheapest smart lipo charger and battery that we
would recommend, which puts you over budget.
Whatever you get, the small pack of BBs typically included in the box should go straight in the bin. Really, don't shoot them.
You'll want BBs from here:

e.g.

I know there's a huge range to choose from and this can get very confusing, very fast. Please get back to us if you have more questions, but we won't be able to answer the battery and charger question with absolute certainly, that would be one for the retailer.
G&G Combat Machine M4 rifles are superb entry level guns for about your price range
They
used to be, the prices have gone shooting up recently. You
may still get lucky finding one in-budget, but again, you'll need to add a battery and charger for a minimum of £25.
To keep under a £150 budget, you're really only looking at CYMA, Lancer Tactical, Specna Arms or Jing Gong at the moment.
