I started with a Stuart 10V , which used to be the traditional 'baptism of fire' model for decades, but doesn't seem to be so popular these days.

Well I suppose like the OP the cost puts people off, one of those two I linked do would cost 1/2 -1/3rd, I did work it out for the vertical that I made which is the same size as a No7 and that was 1/4 of the price as the solid flywheel meant it was all barstock.and you also don't have the possible problem of hard spots or undersize castings.
Plus will a lot more people having access to mills and many free barstock designs via the web it is a lot easier to start with a barstock engine.
As there is more machining involved in a barstock engine the beginner will also learn a lot more processes than they would with a casting based engine and as they take a bit longer to make you get more workshop time for the outlay.

I'd say that an engine from a set of castings is actually more difficult to build than a bar stock engine to the same design. The castings are often difficult to grip and set up for machining and you always need to think very carefully how much material needs to be removed from each surface. Plus the as cast unmachined surfaces are quite tricky to clean up to give a nice finish - even if you are going to paint it. Add to the above, the cost of the castings and I am not surprised that people build bar stock engines.

I had a very basic training with lathes and milling many years ago then brought most tooling that's needed over four years. I'm still learning the hard way so bar stock is the way to go for me,l would find castings even after four years a hand trembling experience and mind concentration that I will muck it up, so not yet for me. I started with Elmer's engines which are free on the internet I learnt a lot doing them then done a couple of Potty mill engines. Just the cost of materials needed plus a few bolts and not the worry of mucking up an expensive casting till you feel confident that your ready for that.
Still learning the hard way. Bob.

I have just started my first engine. I decided to build the Muncaster from Jason's recent series in ME magazine.
The only casting is the flywheel which I bought from Lee on eBay as per Jason's link.
I have only made a few parts so far, but I am learning a lot. Progress so dar:

Looking good Stuart, the Muncater is a fine looking engine.
I'm going to start with Gerry's Beam Engine. I have had a good look at the drawings and 3d cad model. Read a few constuction posts. Sadly the photobucket fiasco has ruined a lot of the photos... (I'd love to have been a fly on the wall at that business planning meeting)

You look to be off to a good start Stuart.
