Hi Jimmyybob
Costs!
I went my own way, not using kit, because I simply wanted to do it myself, not because of the costings. As a modelmaker, I get pleasure from the build so it suited me.
Using the kit gives you all the advantages of Richard's knowledge and research and devopement, and evolution.
Going your own way will give you lots of headaches, and often you will need to redo something, if it doesnt quite work out first time.
I kept a detailed account in the beginning but lapsed as I got towards the end, but my costs are close, within a few pounds I think.
Comparing kit price with my cost isn't really comparing like for like.
My cost is the total cost of the build, to where it is now, just some cosmetic finishing required. If you take the kit price, you need to add other costs to make a comparison. Body tub materials, about ?60, a couple of tins of paint, primer, undercoat, matt black, exterior top coat, interior topcoat, soon runs away with another ?50 or more. Then there's batteries and charger and so on.
My total cost was in the region of ?750, which equates closely to the kit price, But I used a second hand invalid buggy, I have second hand batteries, unknown condition!, second hand motor!, on the plus side I have a fully proportional throttle, and drive to both wheels, which would be an extra cost on the kit, but then, I don't have the lighting set.
All in all I think the kit is good value and a good way forward, but the way you go is more a matter of personal choice than the cost.
It depends on your expertise, experience and available facilities, and of course your spare time!
I'm retired, and I spent a great deal of time on the project, it took nearly 3 months from ordering plans, to where I am now. Although I too spent a long time pondering the way forward before I actually started.
Sorry for long winded reply, but hope it helps you decide which way to go, either way its a great project, great feeling when its complete, and great fun for the kids, so don't delay, get the wood ordered up and get started. Put some heating in your workshop and keep busy!
Always ready to help
best wishes

PS that includes ?200 for the invalid buggy, you can get them cheaper but I used my wifes buggy and ?200 bought her an identicle replacement!
