I abandoned EAGLE and now use DesignSpark PCB

How does it work compared to Eagle?

I have been a loyal Eagle user since version 2.61 for DOS (1993).

The size of Tubelab PC boards require the PRO version, and Cadsoft wants over $1000 for the upgrade. Upgrades were $100 to $200 before Newark bought the company. I am on version 5.11 and it will not read any of the libraries from version 6 or 7.

I realize that a $1K upgrade is cheap for a large company with an fat budget, but it is way out of my league for simple two layer PC boards that just happen to be big.

I tried DesignSpark when it first came out a few years ago, and it pretty much sucked. Maybe it has improved in 5 years?
 
Well...DesignSpark...once I got the libraries sorted out and learned it's idiosyncrasies I can definitely make it work for me.

Luckily (I guess) I learned after I had just one board made under Eagle (a cap board) that I had to get another program to do tube work due to the small size pcb limitation of Eagle. I had never used a pcb program prior to using Eagle and also went a few months after learning Eagle of no pcb program work so it would be easier to "transition".

There are several tutorials online by the DS folks and others that helped also. At this point, I know more DesignSpark than I ever did with Eagle but still consider myself a novice at it.

It seems the DesignSpark autorouter does suck but I never really got the chance to use it under Eagle. Maybe all autorouters suck.

They seem to put out a new rev. of DS a couple of times a year.

There is a way to import Eagle designs into Eagle but I never tried to make it work.
