Identify the exact model, version and year before comparing prices

Before comparing prices or condition, you need to know exactly what you are looking at.

Whenever possible, verify:

• brand and complete model name;
• series or generation;
• year or production period;
• country of manufacture;
• hardware or firmware revision where relevant;
• original configuration and finish;
• any special edition.

Two products with almost identical names may use different components, specifications and market values. Serial numbers, labels, rear panels and construction details can help distinguish versions.

Only after correct identification does it make sense to compare the price with genuinely equivalent examples.
