Not the OP but have avoided Packt books for years: I find them to typically exhibit quite low quality of writing and I assert without proof that they lack the rigor in the editing process that more 'serious' publishers have. Also I think it's pretty easy to become a Packt author; some people I've worked with and a friend have been approached by them. Typically I only buy Manning or O'Reilly but I've read a few garbage titles from the latter of late so I suspect that might not hold for much longer. It'll be interesting to see if perceived quality becomes a market differentiator or if tech books at some point become unprofitable.
