I use Electrical Estimating Pal. It's like $10 on Amazon. It's sufficient for small resi service, but you have to build assemblies yourself. Note that any new work is going to be at a difficulty multiplier beyond what the book states, or you need to add certain task-items (eg fishing cable, drilling in a tight spot). But if it's unfinished space, the numbers are fine as-is. Probably not a super-tight bid anyway and a bit of padding doesn't hurt.
Start there and track your own hours/time for larger tasks. Adjust as needed.
I've used Accubid for multi-million jobs. The numbers aren't really different much from EEP's. NECA/etc definitely are fluffed. Accubid came with its own proprietary database that was more inline than NECA's. I've heard the 0.8x NECA thing a lot.
I wouldn't use EEP for new builds or commercial though. Buy a proper program. I don't recommend Accubid, but it works certainly out of the box.
