Speccy2010 jest mniejsze, nie ma VGA, nie wiem, czy ma covoxa, nie ma FDD.
Tu opis od Shiru (trochę updateowany), kupy się raczej trzyma, chociaż chyba nie wszędzie.
___________________________
ZXEvo - FPGA-based reconfigurable clone (upgradable without soldering), with real Z80, AY, FDC. 3,5 / 7 Mhz, 4 MB RAM. Covox implemented. It could work as Pentagon (PentEvo), there is also development of Scorpion mode. It is miniATX board, with connectors for PS/2 keyboard and mouse, floppy, IDE, SD card, RGB / VGA output (requires display with 48.8 Hz support). Available as a kit and as assembled board, but there is a pretty long queue for the assembled boards. Reads TRD/SCL/TAP.
~$100

ZXM-Phoenix. Old-style clone for those who don't like modern technology, such as FPGAs, with a lot of discrete logic ICs (71). 3.5 MHz (means no turbo mode), 1024 KB, AY, FDC. mATX board, PS/2 keyboard and mouse, floppy, IDE, no SD card. It is not Pentagon-compatible, so it is not suitable for looking old demos. From time to time there are batchs of boards (~$25, empty board) and kits produced, no assembled boards available.

Speccy2010. Successor of Speccy2007 (popular modern very simple 48K/128K clone), fully FPGA-based, up to 32 MB. Currently 3.5/7/14/28 MHz, 128K, AY, Pentagon timings, PS/2 keyboard and mouse, no floppy or IDE, SD card (TRD,SCL,TAP,TZX,SNA but NO flash-loading of TAP/TZX at the moment). It also has no ROM at all, everything is configured from SD card. VGA output is in development. Unlike other clones, this one has very small board, not designed for PC case. Like ZX-Phoenix, it is not produced in assembled form, empty board is ~$8.5, and components are ~$58.

There is complete docs available for all these clones, so you can build them by yourself as well.

Ja tam polecam głównie ZX Evolution i tyle.
