I can help you with that one as well DELBOY...
I have been using in-ear monitors exclusively for around 3 years now and have never looked back
Not only do you get ear damage protection but as you have found you can tailor your monitor mix
Hear is the route I have taken...
In-ear "earphones" I use are Shure 315s
https://www.thomann.de/gb/shure_se315cl.htm I got mine from eBay as I wasn't going to use anyone else's ear tip...
To get the true "in ear monitor" experience you really need to have custom moulded earphones so that they fit your ear canal perfectly - this gets really expensive and is what the pros use
However, if you get the shure earphones you can have custom ear tips made that can be put on the shure monitors to give you a full custom in-ear monitor setup for a fraction of the price of the pro sets
The best company in the world making these happens to be literally down the road from me:

If you do want to go down this route let me know and I would be happy to help out
I will probably go for a mega set if/when mine break - in ears are awesome!!!
No monitors to fall over, less volume on stage (no monitors), hearing protection, better monitor quality, individual monitor mix etc.
I love 'em
I know our sound guy did a lot of research into the wireless packs, which weren't too expensive, but I can't remember what they are called
I am gigging in Chatham, Kent tomorrow (if anyone fancies coming down) so will check
