Yes, that price is more than acceptable ;)
The danger might be that at low prices the demand might be quite high.
I'd take five for example.
Andy, are you soldering them manually?
Any other plans for the coming years? :mrgreen:
In theory, there is no difference between theory and practice. But, in practice, there is.

I would like to buy some. Any idea (roughly) of price yet? :D
ordered parts and added everything up... think we will be looking at £15 + P & P
3 units please! They could be in DIY kits if it helps.

Can Sell my Retro be used for preorder? Then you will know how many to produce.

I have ordered 100 PCBs i don't forsee any problem getting hold of components, passives have been ordered in bulk ( relatively low price ) I have cplds for 30, but will likely order more immediately. Yes I am hand soldering them, getting rather proficient at those 0.5mm pitch qfp :mrgreen: I have included a few quid in price for my labour time.

Perhaps a bulk order for our German brethren can be worked out that would at least save some postage costs.

@Andy, if you up the price to say £30, you could almost retire at this level of demand :lol:

Of course, you would want someone who suggested this idea not to loose out, so would supply him (me) with a couple of units at cost price (£15) ;)

For you Mark I'd be quite happy to do a BOGCT offer... For clarity that is Buy One Get Charged Twice :mrgreen:

However it's not really my intention to become rich, I believe a fair price that includes something for my labour is better for everyone.
