Std dry sump kit = £1235
Tank. = £ 300
Hose+fitting. = £1000
( depend on what you have in the system and where the tank is placed )
Good quality oil cooler = £100
Good flowed remote filter head = £50
Then there's hose clamp/tank mounts and all the other Hiden bits you don't know about till you fitting a kit .
Not saying every one will spend this much and there are bargains/discounts to be had , but if you do it right it can cost .

Remote presure pump kit + modded pan/pipes/fittings/oil in plate/pulleys/belts/and there maybe one or two other bits = £1000
( price is not a 100% yet so there is a good possibility it's a bit less)
The pump itself is nearly the same as a dry sump one just minus 4 gears and 2 stages which only makes the pump a little less to produce as it still needs 1 front 1 prv 1 prv housing 1 spring 1 prv adj assembly 1 stage 2 gears 2 fittings 2 harden/ground shafts 2 bearings 1 seal 5 needle rollers and so on ( got bore and can't be bothered to list any more bits) but I assume you can see where that was going ,

A kit has been tested and just awaiting some more info/ feed back then another kit will go to Ian howell for him to give me feed back then I will make a load
