I kinda disagree with the more work part.
I guess it depends if you already have the chemicals to etch boards or solder paste and oven/some heating solution to solder surface mount resistors.
Or if you have the patience to wait a couple of weeks to get some custom pcbs made.
I'm looking at sleemanj's pictures and I can't see myself soldering those smt resistors on the pcb, I'd waste a lot of time doing it manually and I'd get bored with it.
In contrast, I'd just use one of those
plastic lead former tools to just prepare some 1/8w resistors in advance to the same lead size, stick the leds in the holes evenly spaced, flip the pcb and start soldering. And I can use the leads I cut from resistor to make jumpers between two 3-hole pads and form power buses where needed. Or I can just get some solid core network cable, strip the insulation and solder the wire across the pads i want to connect together on the other side. Super fast and easy.
And in the case of first proto board pictured in my previous post, being symmetrical on all sides and covering the whole 160x100mm, it would be easy to connect them together with straight or 90 degree 0.1" connectors.
5 pounds, 7.5 dollars... it's a bit expensive. As mrflibble says, you can get 10 pcs 150x100 for $48, it would cost you 75$ for 10 such protoboards, about 80$ with shipping.. but I can get them to my door in 2 days while i'd wait three-four weeks for itead.
But you don't have to buy them from farnell, you should find the model with a bit of search on ebay.
