I personally do not consider Kits DIY, Just like "Paint By Numbers" isn"t art and a Lego isn"t Construction....
Kits are closer to "Paint my Numbers" than they are to DIY and many Times after finnishing a Kit you haven"t learned a single thing about electronics just like after finnishing a "Paint By Numbers" kit you aren"t any more of an artist, You are just following instructions which anyone who can read can do....
If you really want to do a real DIY project go find a Good preamp schematic and then design and Etch your own PCB and then source your own Parts and troubleshoot any problems yourself....
You should find that after doing this that you will feel much more proud of what you have accomplished and you will have learned a great deal more than any "Kit" could teach you and you will have saved a Lot more money than Buying a Kit, Sure it might take quite a Bit longer to build but most real DIY will take longer and take a Bit of brain Power......
Cheers
