Bargin HP is harder to find here in europe, they are around but not cheap or common.
Shipping from USA is expensive, plus you would have to make sure it is dual voltage.
Try looking for Thurlby/TTI, Weir or Farnell PSUs
The Thurlby PL320 is a classic 30V 1 or 2A linear with voltage, current control and it has an output on/off switch, perfect for a beginner.
They are very common on ebay, just make sure seller says is in PERFECT WORKING ORDER, there are plenty with faults.
