I've ordered the E3D already - being UK made and living in the UK it's relatively inexpensive to get hold of one considering - It just makes sense to me that Instead of building the unit and then having to disassemble and modify and recalibrate in about a month or so (worst case scenario) - it would be logical to build it right from the get go with the E3D hot end and then there would be no limitations to printing materials (within reason obviously) as compared to the stock hot end which could be relegated to the parts box as an emergency hot end replacement should it ever be needed.. and I've ordered a hot end 40w cartridge for it as well should the need arise - (been difficult find a screw mounted thermistor though in the UK presently) - though I reckon you could adapt the stock hot end to fit the thermistor the same way E3D do with a little bit of work
Yes I am new to the 3D printing scene as far as hands on Knowledge is concerned - but I've been professionally modelling for 3D printing for a few years now - it's time I get some hands on experience and returns from some in house equipment

- (especially considering the demise of the last few patents and the good tech that will appear in a year or two a sa result) and I'm fairly handy as I have electrical / electronic experience to Grade 2 HND from my distant past coupled to about 20 years of building PC's and other equipment semi professionally - coupled to the fact I'm a stubborn sod when it comes to learning new things - which is a good thing I suppose
I'm very much looking forward to the project when I can get started

I'm currently scouring these forums and making notes diligently in preparation
