One of the lads I bash with has an electric 5T (amongst many many other models) and its a very nice rig, it jumps better than the petrol version and handles really nice as the weight is better distributed and low down, down side is that he gets 25mins from a pair of 6500mah 4S Lipo's.
I have an electric 6th scale rig that when I take out just gets abused from word go, its easier to use than the 2 stroke stuff and can be taken to the forests etc but its not quite as fun as my truck even if the truck is slower.
I would think really hard about going for an electric rig, the rig itself will be cheap, but when you factor in £75 for a charger, then £300 in batteries to run for an hour at a time then charging batteries for the next 3-4 hours, that side of it stops it being fun as is why I barely take mine out. If I'm going for a bash on the field down by my house I'll grab my truck, throw a tank of fuel in it and go bash for 45mins.
ps my electric rig is a cheap FS Racing buggy running 6S, is 4wd and is now pretty much fully custom (cost me £250 all in). I'd hate to think I'd dropped £1000 before batteries.
I think it being electric means you bash it like a 1/10 or 1/8 scale rig which they aren't designed to be bashed that hard.
I'd put the money to one side for now and see if the itch is still there in couple of months.
