Canon V-30F MSX2
It's a bargain, but you'll have to reverse engineer the keyboard 
mars: do you have evidence of the V-30 specs?
Also, the Canon V-25 only has 64kB VRAM, while the V-30F at least has 128kB VRAM.
You can find a picture of the V-30 (without F) on this ASCII page :

It's the machine on the right and when you enlarge the picture, you'll see there is only one drive (and the place to install a second drive) :
キヤノン『V30』（写真右、'86/03）
キヤノンのフラッグシップMSX２。大人の女性を意識した白基調の上品なデザインでした。別売の本格ワープロソフト『V-WORD』（3万4800円）との組み合わせで、「SOHO」需要にまで応えようと試みました。13万8000円。
Google translation :
Canon "V30" (photo right, '86 / 03)
Canon's flagship MSX2. It was elegant design of white keynote-conscious adult women. In combination with the full-scale word-processing software (sold separately) "V-WORD" (¥ 34,800), it was attempted to live up to the "SOHO" demand. ¥ 138,000.
Yes, but we cannot see the amount of RAM or VRAM... Also, it's not clear from the image that it isn't a V-30F after all (you can't read the type number)... The pic on GenMSX for the V-30 has 2 drives, but it may also be a V-30F picture. Not very clear... 
Hmm, I found an image of a V-30F advertisement, where only one drive is visible in it... See
