I'll admit. I typically recommend more expensive parts as opposed to the cheaper alternatives since it tends to save more money in the long run.
But I do appreciate finding quality parts for less money
I built my Durga using Tony's Screw Kit (it is excellent). The perfect tool set is the Dynamite Hex Driver Metric Set [

You will need all three drivers for the screw set (1.5mm, 2.0mm, 2.5mm). This is a high quality set for only $20.00 and you can often find it on the shelf of your local hobby shop. Make sure to grab the Metric set. Dynamite sells a 'US' set that looks identical, but they won't fit your kit.
The only problem I had with screw kit was with the screws used to hold the motor mount to the chassis (this was not a concern since these screws are going into pre-threaded metal and not the hard plastic). For some reason they supplied screws that were a little too long and prevent the center belt cover from seating properly. You can either dremel these down or use the kit screws. All the other screws that you need to drive into the plastic measured perfectly.
The Tamiya brand Hop-Up shock kit is the best one around for the Durga - they are built like a tank and will not let you down.. One warning though, the upgrade shocks are -too long- for the Durga or the Baldre by default. Tamiya does not mention this in the assembly instructions for some reason??? The are so long in fact that they will cause the rear uprights to rub against the inside of the rear wheel hubs every time the car is airborne. This will eventually cause the uprights to crack in half (yup, it happened to me during a race). The solution is to put limiters inside the shocks before you build them. This is done by sliding a couple rubber o-rings on the shock shafts before you fully assemble the shocks (they will be on the inside of the shock cylinder). It will save you a lot of time and money if you do it first thing.. Use the length of the kit shocks as a guide. The hop-up shocks should measure the same length as the stock shocks (eyelet to eyelet) when they are fully extended.
I've been racing my Durga in Novice and Stock class for several months now and I live in the USA. I'll be happy to help with other questions you might have. Let me know.
