Oh, it became quite lenghty during my absence, so I'll try to answer in one longer mail 
Elfen - it is Lombard aka "Bronze keyboard" G3 version that I was thinking about. I want choosen machine to run OS9 natively. SCSI is rather not needed as I have in my PC (ironic, isn't it?).
And yes, I was in touch with J English Smith (very nice person BTW), but he has only one 1400cs/117 left with FDD only. And I was afraid about eventual system reinstall, as I don't have any Mac with FDD drive (I have one USB, but with Mavericks on MBP it is possible only to use diskettes in R/O mode...). And of crouse shipping costs are high. There is alternative to USPS Polish service (they ask about half of what USPS used to charge for this), but it is not available in J English Smith's region...
Gorgonops - I'm thinking about G4 DVI 667 MHz model in nice cosmetical condition (I've heard that from these series at least screen hinges were somewhat improved), with almost no signs of paint peel off. Fragility of these G4s would not be a problem, as I would use it for pleasure from time to time, rather not carrying around (this is my MBP duty).
Trash80toHP_Mini - sometimes it is possible that graphic card could have enough memory, but could not be capable of specific resolutions, especially in case of analog outputs, where specific timings of signal must be pre-programmed. It is usually easier in case of DVI output, where no D/A conversion is needed.
So after reading all of your posts, I'm leaning towards mentioned above G4 DVI, with perhaps a chance for a 1400 in nice shape and reasonable price in the future, with System 7 - mostly for a REAL nostalgia Alas it is not always nostalgia. There are still very productive features of classic OS missing in OSX - like window print, or possibility to automatically mount network disks after system start. Not to mention coding quality. Has anybody ever enjoyed waiting for print preview in Excel 2011? Or turn of wysywig font menu to speed up launch time? Office 2001 apps do it better. No joy.
