Oatley Electronics is another source of PICAXE items :

While Altronics stock PICAXE specific hardware they do not stock i2c EEPROMS. However Jaycar stock these – 24LC16B and 24LC256.
Most electronics stores will stock other parts like LED’s, resistors, LDR’s, 12 and 16 key keypads etc.
While most seem to recommend going the way of a PICAXE-8 series chips as a starter, these are limited, not so much in terms of programming but more so in term of inputs and outputs. If you are not sure whether you will continue experimenting and are limited on finance still a good starter point.
I spent a lot of time 25 years ago programming 8bit microprocessors including a 68705P3 microcontroller (for my own garden reticulation system) so have past experience. I do not have a specific project in mind but am building up my own PICAXE experimenters box so bit the bullet and went straight to a PICAXE40-X1, an AXE022P proto-board and an AXE033 LCD display module with RTC clock option fitted. Costs a lot more up front but not really limited for I/O in the future. About to embark on a 48key keypad using polled interupt to cover alphanumeric input.
