Price is subjective really, especially as many of us are paying between three and eight grand for an electric pushbike loaded up with a component level normally associated with bottom of the range catalog bikes.
The Bullitt is a one piece design properly made, and not welded by someone who learned to weld in some part time evening class and never really done it since or as a job.
It's in alloy specified for the job via computer aided design, and not heavy weight steel tubing, probably selected because thats all B&Q had in stock and the fact welding alloy involved heat treating so steel is easier for the amateur to attempt. Fully and professionally painted, all the parts for attaching the bottles and or batteries and most importantly its been assembled on a jig, so geometry wise its all square. Not an easy thing to do by eye especially if you've no idea how to go about such a process.
Expensive yes, but reliable also. And it doesn't look like a pigs breakfast.
Another thing to consider is no donor bike was really designed with adding 40lbs of steel framing to the front. Which is probably why the OP built his from scratch, and oddly or tellingly enough in the same style as the bullitt.
Front cargo is something Dutch bikes used in the origins of cargo bikes and some of the ones I've seen over there were for carrying huge amounts with a pallet sized platform.
