Jackie.
At playing for two months you have only just started and if you take my advice you will concentrate on learning the craft.
There are plenty of Backing Tracks or even the Original Recording that you can play along with if you so choose, additionally there are plenty of websites that transcribe songs so you can easily use these top find out the chords and progressions used.
Meanwhile look at what is available in the market and save up some more cash, I certainly would not be going out there spending £80 on a Looper and another £150 on a reasonable pair of powered Monitor Speakers, cash spent on a keyboard upgrade will serve you much better in the long tern than add on accessories.
When this CV19 has settled down some more and you have done your research do have a trip to a well stocked Music Store and see what they can offer.
From your quote of £500 you are somewhere in the UK and unless you are in the wilds of Scotland then a well stocked Music Store is likely to be within easy reach. I live in Lancashire and there are about 20 stores within 1 hour travel that I can visit if required.
